DRAFT-EQUALIZER.

SPECIFICATION forming part of Letters Patent No. 459,026, datedSeptember 8, 1891.

Application filed October 10, 1890. Serial No. 367,741. (No model.)

To all whom, it may concern:

Be it known that I, ERNST H. TANK, a citi- Zen of the United States,residing at Holstein, in the county of Ida and State of Iowa, haveinvented a new and useful Reaper-Evener, called and known as the TankReaper-Evener, of which the following is a specification.

My object is to provide a strong, durable, and convenientdraft-equalizer adapted for three or four horses and for any wagon,plow, reaper, and hinder, or other machine that is to be advanced byhorse-power.

My invention consists in the arrangement and combination of operativeparts with a carriage-pole, as hereinafter set forth, pointed out in myclaim, and illustrated in the accompanying drawings, in which Figure 1shows the complete device adapted to be used as a four-horse evener, andFig. 2 as a three-horse evener.

A is a pole or tongue, adapted to be fixed to a wagon or other tractablecarriage.

B is an evener pivoted at its center to the rear end of the pole.

C is a straight Wooden bar fixed to the pole A in advance of the evenerB to extend horizontally and at right angles from the pole.

Braces y and .2, fixed to the pole and the bar 0, aid in retaining thebar firmly fixed to the pole as required to resist the force applied tothe free end of the bar.

E are carriers pivoted on top of the bar 0 to support and carryevenersFand II in such a manner that the carriers and the eveners will haveindependent motion or vibration.

Perforations 1 2 3 in the bar 0 and metal plates J, having correspondingperforations placed on top of the bar and bent upward to overlap theends of the carriers E, and bolts passed through the coincidingperforations in the straps J, carriers E, and bar C, produce a stronghinged connection between the carriers E and the bar C.

D and G are rods and links combined to produce flexible connectionsbetween the ends of the evener B and the central portions of the evenersF and H and the ends of the carrier E. The front ends of the flexibleconnections D G are attached to clevises, and a carrier E and evenerjointly connected with each of the clevises by means of a bolt passedthrough the eyes of the clevis and through perforations in the evenerand carrier.

Blocks L, fixed across the bar C and under the pivoted carriers E, serveas bearings to support the free end of the carrier E, elevated, asrequired,to prevent it from rubbing and wearing the top surface of thebar C.

I claim as my invention An improved draft-equalizer comprising a bar 0,fixed across the top of a pole A, bars L, fixed across the top of thebar G, evenercarriers adj ustably pivoted to the bar 0 by means ofperforated plates J, eveners F, pivoted to the free ends of the carriersE, and an evener B, pivoted to the rear end of the pole and its freeends connected with the eveners F and carriers E by means of rods and.links, and all the parts arranged and combined to operate in the mannerset forth, for the purposes stated.
